Visual Bug - During playback, cresc. dashed lines will disapear as the playback bar goes past them.

During playback, the dashed cresc. line will disappear as it moves past it. It seems to me that it specifically relates to when the playback line actually touches the cresc. line, as the CB part isn't affect by this as the playback line does touch the CB's cresc. Upon stopping playback the lines reappear, so this is only a visual bug and doesn't actually get rid of them nor does affect the playback of the cresc. itself.
